IMPROVEMENT IN NOTTS STOVE.

Specification of Letters Patent No. 1,260, dated Jul V26, 1839 T0 (ZZZ about it may concern.

Be it known that I, ELIPHALET No'r'r, of Schenectady, New York, have invented Improvements in Notts Goa-LStoves, of which the following is a specification.

Figure 1, longitudinal section of stove, having an angular chamber of combustion and its inlet for fuel in front; a, ash pit; Z), rotary cylindric grate; c, chamber of coinbustion; (Z (Z, brick plate side walls; 6 6, space between brick plate walls and outer covering; 7 f, outer covering; 9 g g, door for fuel; it, flue; Fig. 2, transverse section of stove, having a brick plate chamber of combustion, an inlet for fuel at top, and an internal flue for flame; (z, ash pit; Z), rotary cylindric grate; c, chamber of combustion; (Z (Z, brick plate side walls; 6 e, space for air to circulate; f f, outer covering; 9, brick plate follower; Z1, lid; 2', arm on lid; Za, arm on ventilator m, against which Z strikes as Z2 shuts and by striking raises and shuts m, the ventilator; a 91, internal flue for flame; 0, hollow brick plate prism forming lower front of flue to be used if preferred in place of a solid brick, as is now in use; p 7), iron plate forming upper front of flue to be used if preferred in place of solid brick now in use; Fig. 3, rotaryflat grate (to be used at b in Fig. a) Z) Z), outer bar or rim; a a, circular grate bars; 0, re-

movable or stationary handle projecting through a slit in the crust of the stove for rotating the same; Fig. -l, longitudinal section of stove having a cylindric brick plate chamber of combustion and a fiat horizontal rotary grate; a. ash pit; b, rotary.

grate; chamber of combustion; (Z (Z, brick plate cylinder forming chamber of combustion; 6 (a. space for air to circulate; outer covering; (j g, feed door; It, flue; Fig. 5, elevation of Fig. 2; (1., ash pit; Z), lower opaque part of chamber of combustion; (1, illuminated sash covering front grate; (Z, second story; 6, cast iron flue; f f f, entablature; g, valve in an oblique position by which the flame when shut is turned down ZL or when open passed direct to Z 72. down fine; i 1', flue from Z2 to Z1, an up flue; Z, escape pipe; Fig. 6, a specimen of brick plate; a a, outer margin; (2 c, spiculae; Z) Z), holes between spicules.

The improvements exhibited in the fore going drawings consist, 1st, in connecting (as exhibited at h, i, 7.1, and m, Fig. 2) the cover of the stove with its ventilator in such nianneiwthat both-shall open and shul= ;-together, by projecting from the coverlz-jarms i, that-interlock with projections 1 onthe ventilator m, or by any-other -devie"epreferred; 2nd, in forming the chamber of combustion with brick plates, that is with plates covered with spiculae, or pierced with holes at small distances, or both covered with spiculae and pierced with holes, as exhibited at (Z (Z, Figs. 1, 2, and 6, the interstices being filled with clay or clay and sand and the fire face thereof being washed with a solution of alkali and salt, it being understood that for the purpose of holding the clay or composition lining firmly in its place the spiculae should be a little inclined to or from each other, or if parallel to each other then inclined to the plane of the face from which they are projected, and also that the spiculae should vary in size and length according to the thickness of the brick plate 111 contemplation, and it beingalso understood that said brick plate may constitute the only side walls or that an outer-covering may be added and immediately adjoin the inner one or adjusted at such distance therefrom as to allow the free circulation of air between the two, as exhibited at e 6, Figs. 1, 2 and 4c; and it is also to be understood that the brick plate chamber of combustion may be either a hollow cylinder and cast solid or it may be cast in separate brick plates either plane or cylindric, and put together, if plane, in such manner as to form an angular hollow prism, as exhibited at (Z (Z, Figs. 1 and 2, or if cylindric in such manner as to form a hollow cylinder, as exhibited (Z (Z, Fig. L; 3rd, in making use of a hollow brick plate cylinder or prism in place of solid brick for the front of the internal flue, as seen at 0, Fig. 2, said brick plate being constructed or made, as in the flat plate, with spiculze, or holes, to retain the fire clay or composition; 4th, in making use of the b i k plat-e for the follower where one is in use, as seen at 9, Fig. 2, said follower being in other respects similar to that formerly patented by me; 5th, in making use of a movable grate for sifting through ashes or emptying residuum in combination with a brick plate chamber of combustion, which grate may be cylindric and have a vertical rotary motion, as exhibited Z). Fig. 2, or flat and circular, as exhibited Z) Z), Fig. 3, and have a horizontal rotary motion, as exhibited in place at Z),

. Claims:

1. I claim the connecting of the cover and ventllator 1n stoves 111 such manner that the two shall open and shut together as above set forth.

2. The making use of brick plates for the Walls of chambers of combustion in stoves and furnaces Whether angular or cylindric constructed as above set forth.

3. The making use of a hollow brick plate prism for the lower front of the internal flue as above set forth.
